( Figs. 86–89 )

Plocoscelus setosus Hennig, 1935: 49 .

Description: Body length 6 mm, wing 4 mm. Palpus mostly dark brown, white on outer face. Clypeus brown, with sparse pale microsetulae. First flagellomere dark brown covered with pale microsetulae. Fronto-orbital plates and frontal vitta brown. Epicephalon, vertex and paracephalon black. Postpronotal lobe black and shiny. Row of katepisternal setae brownish. Hind femora narrowly white basally. Fore tarsus one dark brown, 2–5 white. Oviscape dark brown and shiny, apex yellow. Epandrium yellow.

Head: Palpus broadened basally and gradually tapering to apex. Clypeus short, length less than half of width. Three frontal setae. Frontal vitta slightly prominent, shiny. Epicephalon with golden pruinosity. Vertex flattened and somewhat pronounced posteriorly. Inner vertical seta insertion flat, without tubercle. Paracephalon smooth, without swelling (not extending beyond the vertex). Line of black supracervical setae strong.

Thorax: Mesonotum with golden pruinosity. Scutellum upturned, triangular. Femora with sparse black setulae. Mid and hind tibia flattened, but sulcus on outer face weak. Wing with stigmatal and discal bands, apex entirely dark. Crossvein r-m clear. R4+5 and M1+2 ending separately in wing margin. A1+CuA2 as long as CuA2. Female cervical sclerite smooth, without swelling.

Abdomen: Tergites with brownish setulae. Female abdomen: Single spermathecal duct uniformly thick, ending in a small spherical spermatheca. Paired spermathecal duct striate and uniformly thick. Paired spermathecal duct stems thin in basal third, apical two thirds bumpy and strongly convoluted ( Fig. 87 ). Paired spermathecae cylindrical and convoluted, broader than paired spermathecal stems. Male abdomen: Ejaculatory apodeme thick, bigger than epandrium and with a broad blade, wider than sperm pump. Phallapodeme extending to anterior limit of hypandrium (somewhat displaced on Fig. 89 ). Distiphallus long, longer than epandrium. Distiphallus with a phallic bulb subequal in length and width. Distiphallus ending in a short and curved distal distiphallus.
